HT-220 is an all-in-one carbon dioxide measurement and control machine, which can collect CO2, temperature, humidity, and illumination in the air environment in real time and display the data on the OLED screen, and can control the opening and closing of the carbon dioxide application system/fresh air system according to the change of carbon dioxide concentration and time. The alarm value and alarm dismissal value can be set freely, and the control device can be turned on and off.
The instrument is equipped with two active control voltages of AC220V as standard, which supplies power to the carbon dioxide application system/fresh air system and other equipment; Optional Modbus RS485 bus digital signal output or a 4-20mA analog current signal output.
The instrument is equipped with a time-sharing control function, which can control the opening and closing of the carbon dioxide application system/fresh air control system in different time periods, and can freely set the control period according to its own situation.
